#DublinPort - Three hundred years ago this week, the decision was made by the Dublin City Assembly to build an embankment from Ringsend into Dublin Bay, in an effort to solve the centuries-old problem of silting in the main channels into Dublin Port.
As RTÉ reports, Philip Bromwell has commemorated this historic occasion with a special multimedia report on the engineering feat, which today extends some 4km to the Poolbeg Lighthouse.
When completed 80 years after plans were first announced, the Great South Wall was the longest sea wall in the world.
And it's still a vital part of the city's infrastructure, helping – along with its sister Bull Wall on the north side of the bay – to keep the port's waters clear of silt and sand build-up for shipping traffic.
But it's also a popular recreation spot for walkers, cyclists, anglers and anyone looking to take in the spectacular vistas of the bay in the shadow of the iconic Poolbeg chimneys.
